The working principle of

　　This product is the special cable for oil well heating, which is suitable for under the rated ac voltage of 450/750v, fixed and installed in the oil well, heating the oil well and the hollow sucker rod or supplying power to the underground electric heater. Therefore, the underground temperature and the recovery rate are increased.

　　Oil heating cable is suitable for the "three highs" (high colloid asphalt, high wax content, high freezing point) oil field well drilling, electric paraffin method is the use of electrical energy into heat energy, through the compensation from the reservoir fluid flow into the well n the heat loss of the way, keep the fluid temperature is higher than the wax precipitation temperature, prevent the precipitation of wax, has reached the purpose of paraffin.

Mainly include:

　　1. Thermal cable method: in the well of the special three-core cable, the electric energy is converted into thermal energy, and the oil flow is heated by the heating of the cable. The disadvantages are low power consumption, high cost and high requirement of cable protection and insulation.

　　2. Electric heating rod method: the electric heating rod is mainly composed of variable buckle connector, terminal, hollow rod, integral cable, sensor, electric light rod, hanger, etc. It is mainly through the cable and the skin effect of heating rod body, achieve the goal of paraffin removal. Its working principle is: the three-phase ac telex to the electric cable inside the hollow sucker rod, cable to generate heat, within the tubing on the entire heating crude oil, increase crude oil temperature, to prevent the tubing in wax, to improve the flow property of crude oil, improve the efficiency of heavy oil exploitation. Of or by cable and hollow sucker rod series circuit of heating, the wire and cable through the hole on the hollow sucker rod body, connected to the book 11 breast hollow bottom, when the ac supply, to plunge into 11 since the tl hollow wall heating. To crude oil plays a role of drying, paraffin removal.

　　3. Underground electric heater: when the special heater is electrified in the well, the electric energy is converted into thermal energy to heat the oil flow.

　　When applied, when the thermal cable is connected with the human well bore under oil bamboo or the electric heating pole is adopted, the heat released by the cable or electric heating pole can improve the fluid flow and the temperature of wellbore equipment, and melt the deposited paraffin, so as to remove the wax.

　　This series of cables are manufactured by Q/ wddoo3-2009 oil well heating cable. They can also be specially designed according to the requirements of users and manufactured according to the agreement of both parties.

　　There are also two new ways to add oil. These two cables are in production operation.

　　4. Load-bearing detection cable used for combined test of water-injection and pot-driving operation, type :WIB 1 3.SQ 1*0.2.

　　5. The high-power ultra generating wave cable which USES the ultrasonic cavitation principle to increase oil, the model is :WIF 1 16US 1*20.

　　Oil well heating cable varieties

　　This product is mainly divided into a single - core circular section structure and blue - core steel wire armored two structures.

Heating cable benefits

　　1. High thermal efficiency, the direct conversion of electrical energy into thermal energy is almost all transmitted to the heating liquid.

　　2. It can reduce the operating load of oil production equipment, improve the working status of oil production equipment, and save energy and reduce consumption.

　　3. It can effectively prevent oil well waxing and reduce crude oil viscosity, thus reducing sucker-rod breaking, improving oil well production and prolonging pump testing period.

　　4. The heating three-phase load balance of the device has no influence on the power system.

　　5. The oil well heating cable has strong tensile resistance, high temperature resistance, abrasion resistance and stable performance after repeated operation.

　　6, its long-term heating working temperature 90 ℃ respectively, 105 ℃, 205 ℃ and 250 ℃.
